You have to keep challenging yourself. I've always tried to do that, and I'm not saying I've always been successful. Maybe I've rewritten the same song; it's inevitable, but I've always been mindful of taking the writing somewhere else. You can't stick in your little comfort zone.
I was nominated for two Grammy's, but. . . more importantly, I like it when I get a letter from someone. . . a person that I've affected their lives or I've helped them. That's important to me. Someone will say "I was feeling bad and you helped me".
